Title: Foods having grain shells and non grain interiors
Inventor: ZUKERMAN HAROLD W
IPC: A23G3/54
Filed: 1995-07-11
Abstract: A process for making food products having outer shells comprised of visible, fully cooked cereal grains which retain their individual identity and interiors comprised of foods that are substantially without cereal grains. The outer shell is made by cooking cereal grains at temperatures over 190 F without excess water so all the soluble gums and starch binders are absorbed into the grains. The grain cooking is stopped by cooling the grains before the grain centers become fully gelatinized The interior component of the product is prepared separately and comprised of foods that are substantially without cereal grains. The units having grain shells and non grain interiors can be formed by several methods: 1) The shell component of the units comprised of visible, cooked cereal grains are formed and baked or fried before their interiors are filled with non grain foods. 2) Coextrusion. 3) Depositing and then enclosing the non grain interior food components between two preformed sheets comprised of visible, cooked cereal grains. The units formed by the coextrusion and preformed grain sheet methods are heated by oven baking or fat frying until the centers of the grains in the shell become fully gelatinized, and the previously wet grain shells become firm. The units comprised of grain shells and non grain interior are then frozen.

Abstract: A polycondensation reactor for processing low viscosity polyester or another polymer into relatively highly viscosity polymer comprises a substantially cylindrical horizontal reactor vessel with a polymer inlet and a polymer outlet adjacent its opposite ends and a vapour exhaust opening in the upper side of the vessel at its outlet end. A polymer agitator is rotated axially within the chamber and includes plural alternating annular overflow and underflow baffles and multiple perforated film-forming screens disposed therebetween in parallel spaced relation to one another. The overflow baffles are in periphery polymer-sealing relation to the vessel while the underflow baffles have multiple underflow recesses in their outer peripheries, whereby the baffles define a tortuous polymer flow path alternately through their respective polymer overflow and underflow openings to control residence time, distribution and viscosity growth as the polymer flows between the baffles. The baffles and screens are integrally fixed coaxially at their outer peripheries by axially extending wiper bars. Aligned openings in the baffles and screens along the rotational axis of the agitator provide for free flow of volatiles to the exhaust opening.

Patent CA-2168422-A1 (CA)
Title: Method and apparatus for predicting and using the exhaust gas temperatures for control of two and three shaft gas turbines
Inventor: MIRSKY SAUL
IPC: F02C9/00
Filed: 1996-01-30
Abstract: A method and apparatus are disclosed for protecting gas turbines (two- and three-shaft) from damage or destruction during dangerous transients.  In this situation, fuel flow must be reduced, as needed, to keep the exhaust gas temperature below a maximum limit, thereby avoiding damage to blading in the  turbine's  first-stage.    The  dynamic  action  of  the temperature  downstream  of  the  combustion  chamber may  be estimated and then used to correct the temperature measured by thermocouples.  For this approach, the turbine is instrumented with an inlet pressure transmitter and an outlet temperature transmitter.   The method dynamically estimates temperatures downstream of the combustion chamber and reduces the fuel flow rate if the estimated temperature approaches the temperature limit.  Existing thermocouple measurements (EGT) are used as well as the pressure of air exiting the compressor  (CDP) upstream of the combustion chamber.  By employing a first-order lag and a steady-state gain, the measured CDP is used to predict a "correction" EGT signal which is then added to the measured EGT, resulting in a corrected EGT.  Once the corrected EGT has been calculated, its first time-derivative is used to adjust the safety margin between a maximum allowable limit temperature and a lower predetermined temperature set point.
